A senior pro-government Yemeni army commander survived a car bombing in second city Aden yesterday that left one of his bodyguards dead, a military official said. 
General Ahmed Saif al-Yafie, commander of the Fourth Military Region, escaped unharmed when an explosive device planted in his vehicle blew up killing a bodyguard, the source said. 
There was no immediate claim of responsibility for the attack and the military official did not blame any group for the bombing. 
Aden, declared by the government as Yemen’s temporary capital, has been the scene of growing unrest as Al Qaeda in the Arabian Peninsula, long active in Yemen, and the newly emerged Islamic State group appear to be vying for influence in the port city. 
It was rocked by months of fighting this year between pro-government forces and Iran-backed rebels who seized the capital Sanaa in September 2014 before expanding south. 
Supported by a Saudi-led coalition, loyalists have regained control of Aden and four nearby provinces in the south since July as deadly battles persist elsewhere across the country. 
In another sign of increasing insecurity, unknown gunmen shot dead a leading member of the pro-government Popular Resistance militia and two of his bodyguards, security officials said. 
They were killed in a drive-by shooting in central Aden overnight Wednesday and the gunmen fled after the attack, the sources said. 
Ahmed al-Idrisi’s militia is a main ally of the Saudi-led coalition. 
The alliance intervened in the country’s civil war on March 26 in support of President Abd-Rabbu Mansour Hadi’s government. 
The government has been struggling to spread its control over Aden with militant groups exploiting the conflict to make sweeping gains, particularly in southern regions. 
The extremists are occupying government buildings and are frequently seen patrolling several districts of Aden. 
They have carried out several deadly attacks, assassinated government officials, and intimidated civilians. 
Yesterday, gunmen shut down the faculty of engineering at the University of Aden for the second time in a week, and also kidnapped its dean Saleh Mubarak, students said. 
The gunmen, who arrived aboard four military vehicles, forced shut the gates to protest against mixing of the sexes on the campus, students said. 
“No mixing. We had previously warned the university,” the students quoted the gunmen as saying. 
Yesterday, gunmen locked down the faculties of administrative sciences, law, and engineering in an attempt to force students to observe segregation of the sexes on campus. 
Witnesses and local residents say the radical gunmen are loyalists of Ayman Askar, a local militia leader known for his links to both Al Qaeda and IS. 
Last month, gunmen shut down the faculty of administrative sciences and threatened to use force against students if they did not observe segregation of the sexes. 
Almost 6,000 people have died in the conflict and though southern militias and Gulf ground forces pushed the Houthis out of Aden in July and paved the way for Hadi to return, battle lines across the country have been stalemated for months as a diplomatic resolution remains elusive.
